You have been staying with the seven demon brothers for a year now, you have learnt so much about them, their hobbies, family, life stories but they don't know much about you even though you spent time together becoming close forming unbreakable bonds even if love yet they feel different despite what they know you as they don't know your past or family and feel it might be the next step in your relationship with them.
One morning when you accidentally slept in they decided to have a plan to get to know you better to think of things to encourage you to talk about yourself and not be their therapist and was granted permission from Diavolo to stay another year.
However you wouldn't be the easiest person to open up, some may say you will be harder than Barbatos to open up because you purposely dodged the question about your own life for a year now but this time they aren't letting you.
Lucifer, mammon, Beelzebub, belphegor, Asmodeus, leviathan and finally Satan sat around the dining room table eating breakfast plotting till you walked down.
